SIFTER TOP FOR CONTAINERS.

Application filed July 1, 1921. Serial No. 481,857.

T all whom it may concern:

Be it known that I, LoUIs A. VEGENAAR, a citizen of the United States and a resident of the city of New York borough of Brooklyn. in the county of Kings and State of New York, have invented a new and Improved Sifter Top for Containers, of which the following is a full, clear, and exact d escription.

This invention relates to sifter tops for containers and refers more particularly to a sifter top construction for powder cans or-the like.

One of the principal objects of the present invention resides in the provision of an extremely simple and inexpensive means for closing and openin the discharge perforations of the sifter top.

As a further object the invention contemplates a means for associating a rotary closure disk with the sifter top, which means eliminates the employment of a stud or pin for retaining the same in place,

whereby the sifter top and its component parts may be. assembled in a single operation and in an expeditious manner.

A; further object in View resides in the provision of means for positively retaining the sitter top in its opened and closed positions whereby to prevent casual shifting of the same from closed to open position, or vice versa.

lVith the above recited and others in view, the invention resides in the novel construction, combination and arrangement of parts set forth in the following specification, particularly pointed out in the appended claim and illustrated in the accompanying drawing, it being understood that the right is reserved to embodiments other than those actually illustrated herein, to the full extent indicated by the general meaning of the terms in which the claims are expressed and by variations in the phraseology of the same.

In the drawing Figure 1 is a collective perspective view illustrating the elements of the sifter top in juxtaposition for assembly.

Fig. 2 is plan view of the sifter top with the elements in assembled relation and disclosing by broken lines the various positions thereof.

Fig. 3 is a transverse sectional view therethrough taken approximately on the line 3-3 of Fig. 2. p

Referring to the drawings by characters of reference, designates the body of the sifter top which is of cylindrical formation and closed at its upper end by an integral head 11, the lower open end thereof being designed to be associated with the container or can body in any desired manner. The body 10 at its juncture with the head 11 is provided with an arcuate bead 12 the ends 13 and 14 of which are spaced apart thereby providing a concentric depression 15 which communicates with the space 16 between the ends of the bead. The head 11 is provided with a concentric annular series of discharge openings 17 in the depressed portion 15. The depressed portion 15 is designed to receive therein a rotary closure disc or dredge 18, the same being of a diameter to snugly fit within the inner periphery of the head 12. The closure disc is provided with an annular concentric series of discharge openings 19 and is provided with a radially projecting lug 20 having a down turned extremity 21 which constitutes a manipulating handle. The lug 20 projects through the space 16 and extends beyond the outer periphery of the head 11.

A retaining cap 22 including a head 23 and a depending arcuate flange 24 is designed to fit over the upper end of the body 10 with the lower edge of the flange pressed inwardly as at 25 under the head 12 to hold the same in place. The opposite ends 26 and 27 of the flange are spaced from each other a distance approximately equal to the distance between the ends 13 and 14 of the head 12, said ends 26 and 27 coinciding with the ends 18 and 14. The closure disc is provided with a central depression 28 which receives the centrally arranged downwardly struck lug 29 of the retaining cap. "By this arrangement it will be seen that the closure disc or dredge 18 is rotatably confined between the retaining cap and the upper end or head 11 of the body of the sitter top. The retainin cap is provided with anannular series 0 discharge openings 30 which register and align with the openings 17 in the head 11 of the body. The openings 19 in the closure disc or dredge 18 are designed to reg-- ister with the discharge openings 17 and 30 when the lug 20 is disposed centrally of the space 16, and are designed to be disposed out of registration therewith when the closure disc is rotated to bring the lug 20 into contact with either of the ends 13 and 26 or 14 and 27 of the bead 12 and flange 26, which ends constitute stops therefor.

In order to provide means for frictionally maintaining the disc in its rotated positions, the head 11 is provided with diametrically disposed depressions 31 and the closure disc with diametrically disposed series of depending teats 32. When the central teat 32 of each series snaps into the depression 31 the lug 20 will be frictionally held in a centralposition in the space 16 and the openings 19 therein will be in alignment and reg istry with the openings 17 and of the head 11 and retaining cap 23. When either of the outermost teats 32 are snapped into the depressions 31, the lug 20 will be substantially in contact with the ends 13 and 26 or 14 and 27 to dispose the operlngs 19 out of registration with the openings 17 and 30 whereby the sifter top is closed against the discharge of the contents from the container to which it is attached.

Having thus described my invention, what I claim is:

A sifter top for containers comprising a body including a closed end review with provi ed with a cutawa portion in the side wall thereof correspon 'ng in width to the distance between the extremities of the ,arcuate rib, the closed ends-of the body and retaining cap having aligned perforations therein, and a closure disk having discharge perforations therein interposed between the ody and cap, said disk having a concentric perforation, a concentric depression in the cap engageable with the concentric perforation of the disk, the closed end of the body having diametricall disposed depressions therein and a plura ity of depending teats selectively engageable with said depressions for respectively maintaining the discharge openings in the disk in and out of registration with the aligned apertures of the bod and cap, a peripheral lug on the disk exten ing through the space between the extremities of the arcuate bead and the cutaway portion of the cap.
